Elamur Groupantskg-uk-render
The groupant beside kg/src/uk.rs in the Mova repository: what the code computes, what it never does, how to go back from its outputs, its invariants, cost and checks.
Facts
Implementation material. A Mova code model describes this code at one source revision: partial models, finite checks and their stated scope. It is not a reviewed general exposition, and its labels are shown as written, never raised.
Components
| component | label | where |
|---|---|---|
| approximant | partial | approximant |
| ast | partial | ../syntax.json |
| composition | partial | composition |
| cost | partial | cost |
| descriptant | present | descriptant |
| invariant | partial | invariant |
| tests | executed bounded checks | tests |
Obernants
The typed relations around the forward model: the behaviour complement (what the code never does), the reverse reconstruction (every input compatible with an output) and specialised views.

Per-member synthesis and normalized multiset completeness.
Modeling epoch — 2026-10-31
Source read before tests and models; retained prospective notes accompany the parent. Current evidence uses bounded invented inputs only. This is partial modeling, not proof or corpus accuracy.
approximant
Forward relation
Tokenize text words; skip implicit members; lookup lemma/grammar without NEG; require original indexed normalized form among synth variants; append restored relation prep/quantity and negation; sort and compare.
Executable approximant gap
Exact categorical structure, identifiers, parser decisions and effects have no useful percentage metric established here. No executable surrogate, automatic substitution or 1/2/5/10% guarantee is claimed.
invariant
Invariant and domain
Success equates normalized word multiplicities, not order/semantic role.
Cost and resources
O(B+sum variant bytes+W log W), O(W) strings.
cost
Cost and resources
O(B+sum variant bytes+W log W), O(W) strings.
composition
Composition
Per-member synthesis and normalized multiset completeness.
Tokenize text words; skip implicit members; lookup lemma/grammar without NEG; require original indexed normalized form among synth variants; append restored relation prep/quantity and negation; sort and compare.
The parent invokes scoped transformations through the actual functions named in their source ranges. Children partition useful observations, not a complete semantic proof; boundaries can omit helpers, tests and effects.
models
behavior_complement
Missing synthesis precedes missing-word error; incompatible form precedes multiset mismatch. No implicit word is required.
reverse_reconstruction
Same successful word multiset admits permutations and spelling variants; word positions constrain individual member lookups but not semantic labels.
neg_transport
Mask NEG for lookup; append не once per flagged explicit member.
relation_words
adverbial:prep+case reconstructs prep; quantity:q reconstructs q; arbitrary other relation carries no extra word.
index_domain
None errors after synth lookup; out-of-range gets empty original string.
correctness_gap
A damaged/lost member fails fixture; passing check does not prove correct subject/object attachment.
tests
Evidence
Parent source checks (a fragment inherits only the behavior they actually exercise):
- uk::tests::tokens_strip_stress_and_keep_apostrophes
- uk::tests::render_check_catches_damage
- uk::wave29::failure_precedence_and_real_parse
Selected kg tests: 15 named outcomes, twice debug/twice release, equal sorted outcomes. Standalone actual global/build.rs: 3 named outcomes per run, twice debug/twice optimized; build_child is normally no-op, parent fixture invokes it against isolated synthetic seeds. Eight compiled source mutations (one per source) each compiled successfully and exited101 on the focused assertion; exact source restoration followed by positive rerun.
This fragment's untested branches remain source-derived. No live graph, DB, corpus, teacher, GPU or held-out evaluation was used. Command specs and numeric exits are retained in the external wave29 graphlang receipt. Strict kg Clippy reports existing source lints; see receipt.
